Andrew Odlyzko has a
fascinating and insightful series of articles
on online publishing: His papers are what got me started on my goal of
getting all scientific literature on the web.

Richard Feynman's paper: There's
Plenty of Room at the Bottom, explaining that computers could
be very small (this predates VLSI) and the wonderful 1982 Feynman Lectures on
Computation edited by Tony Hey and Robin Allen: Perseus Books; ISBN:
0738202967 that talks about how much energy, space, and time computations
should take (close to zero), and an inscrutable (to me) introduction to quantum
computing. There is also an out-of-print follow-on Feynman and Computation,
Exploring the Limits of Computers edited by Tony Hey, ISBN:
0738200573.
